NNLO hard functions in massless QCD (2014)
Journal Article
Broggio, A., Ferroglia, A., Pecjak, B. D., & Zhang, Z. (2014). NNLO hard functions in massless QCD. Journal of High Energy Physics, 2014(12), Article 005. https://doi.org/10.1007/jhep12%282014%29005

We derive the hard functions for all 2 → 2 processes in massless QCD up to next-to-next-to-leading order (NNLO) in the strong coupling constant. By employing the known one- and two-loop helicity amplitudes for these processes, we obtain analytic expr... Read More about NNLO hard functions in massless QCD.

On new physics in Delta Gammad (2014)
Journal Article
Bobeth, C., Haisch, U., Lenz, A., Pecjak, B., & Tetlalmatzi-Xolocotzi, G. (2014). On new physics in Delta Gammad. Journal of High Energy Physics, 2014(6), Article 40. https://doi.org/10.1007/jhep06%282014%29040

Motivated by the recent measurement of the dimuon asymmetry by the DØ collaboration, which could be interpreted as an enhanced decay rate difference in the neutral B d -meson system, we investigate the possible size of new-physics contributions to ΔΓ...

Boosted top production: factorization and resummation for single-particle inclusive distributions (2014)
Journal Article
Ferroglia, A., Marzani, S., Pecjak, B. D., & Yang, L. L. (2014). Boosted top production: factorization and resummation for single-particle inclusive distributions. Journal of High Energy Physics, 2014(1), Article 028. https://doi.org/10.1007/jhep01%282014%29028

We study single-particle inclusive (1PI) distributions in top-quark pair production at hadron colliders, working in the highly boosted regime where the top-quark p T is much larger than its mass. In particular, we derive a novel factorization formula... Read More about Boosted top production: factorization and resummation for single-particle inclusive distributions.
